Two menstruating females take exquisite-sized bowel movements (this helps if you eat chili, salad dressing and corn dogs), but do not wipe. Then they tie down their victim and slide their downstairs areas over his face, starting bum to mouth. They then take turns urinating on his face, preferably while he's vomiting.
